CHILDREN/LEGITIMATION: Provides relative to the presumption of parentage

HB 318 amends Louisiana's Civil Code to extend the period for presuming a husband is the father of a child born during marriage or within 390 days after the marriage ends (currently 300 days). This change directly affects children born during or shortly after a marriage termination, and their mothers' spouses. The bill modifies the legal presumption of paternity by lengthening the timeframe for establishing the husband's parental rights. It does not alter other parentage rules or create new obligations. The measure is a procedural update to the Civil Code, not a substantive policy change affecting broader public programs.
